Aman gave a good description of how to get to the place. Trust Aman's instruction instead of googling the address to find the place is best. Basically I simply google map the restaurant that he told me the place was above, and that was pretty easy when using uber as well.
I think Aman has a number of apartments in the building (or the entire building?) because he switched the apartment on the last day, and the pictures weren't exactly the same, but it was just as good.
The place was clean and roomy, and we had a good stay. Aman was out on vacation, but he was very quick to respond on Airbnb, so was able to answer all my questions.
The place was very convenient for food and BTS. Very central. Note the area has thai street food, but most sitdown restaurants are international cuisine.
